Subject[PATCH v4 0/2] Forcibly enable some MISC_ENABLE features on Intel
Date
Intel allows BIOS or the OS to enable or disable some CPU fueatures via
IA32_MISC_ENABLE. I have machines that don't enable fast strings or
monitor/mwait in BIOS, so do it on bootup instead.

Changes from v3:
- Don't display CPU index (and therefore don't break !SMP build)
- Don't display "Failed to enable..." when kmemcheck is on

Changes from v2:
- Don't linebreak printk messages (for ease of grepping)
- Use printk_once
- Update the "Disabled fast string operations" message

Changes from v1:
- Display FW_WARN messages.
- Don't change the kmemcheck message.
- Improve the fast string comment.
- Improve the changelogs.

Andy Lutomirski (2):
x86: Enable fast strings on Intel if BIOS hasn't already
x86: Enable monitor/mwait on Intel if BIOS hasn't already
